Synthesis
of maghemite nanoparticles by thermal decomposition of cryochemically modified
iron(III) acetylacetonate
Abstract
Maghemite
nanoparticles 40–150 nm in size were obtained by thermal decomposition of iron
acetylacetonate, previously subjected to cryochemical modification. The
composition and structure of the obtained particles and the cryomodified
precursor were characterized by the following physicochemical methods: XRD,
thermoanalytical methods (TG, DSC), FTIR and transmission electron microscopy.
Key words:
nanoparticles, iron oxide, maghemite, iron acetylacetonate, cryochemical
modification, thermal decomposition.
